RCS and Blue Label

I have had this account with RCS for almost 2 years. Now since 1st Dec 2023 till 1st May 2024 there has been a R59 being added to my account. I've been trying to sort this issue out since 26th May 2024 because that's when I noticed it. I was charged for a Mobile content subscription for Edgar's SA which I have know knowledge of. I've been calling sending emails no response. I then reversed the debit on the 10th June 2024 to get some action. This is a product via a company called Blue Label but till this day I have never received any of their product. One says its vouchers and the other says it's data. I've asked for proof of enrollment and never received. I was then called by someone in the RCS accounts department who threatened me by blacklisting me. So all I'm asking is for someone to take responsibility for the error they made refund me with payments of R354.00 which was debited on my account since 1st December 2023 till 1st May 2024 for a product which I never received. So I need urgent help to solve this matter as I'm a pensioner.
